Beit known that I, STEPHEN A. HUNTLEY,

. a citizen of the United States, residing at Elkpoint, in the county of'Union and `State of South Dakota, have invented 'a new and use! fnl Improvement in Firearms, of which the 'following is a specication.

My invention relates particularly to automatic repeating shotguns and rides, though not limited thereto. y

My primary object is to provide improved recoil-started vmechanism for automatically' reloading the gun,provision being made therein against harmful and Wearin g movement of the parts relatively to the receiver duriu g the recoil.

In the form shown' in the accompanying drawings the invention com prises a gunthe ings.

In the drawings, Figure 1 is a broken contral vertical longitudinal section showing the position ofthe parts alter the receiver, barrel, and magazine have been carried` back (together) by the recoil and partially restored to their former position by the restoringspring, thebreech-block-operatin g crank having been given a partial revolution during the partial forward movement; Fig. 2, a hottoni plan view of a two-part magazine; Fig. 3, a broken view, in side elevation, showing a detail ofgthe connection vbetween the two parts of the magazine; Fig. 4, a transverse section on line L1 of.

2l and 22, are or sheet metal, riveted to the etocl'r and having guide-channelejc for the sides of the yoke lll to move in. The guide ehown in Fig. 2l is provided with a recees or friet/1; at an angle to and communicating with the guide-channel, and this Slot receives a atop-block ,7s-2, which may be mani-'isolated by button 71:3, projecting through e. elotki in the' stoet'. to obstruct the front portion of its adi cent giiidecliannel fafter the yoke M/ over?. baell io prevent the receiver from 1 eeaeee moving forward when for any reason it is deaired to hold it retracted. A spring-held tapered retaining-pin in the wall of the slot la serves to Aengage a depression in the block and hold it elevated till downward pressure 1 -with inciined ribs or iianges Zwbich limit the upward. movement of ehells being: inserted or extracted, with a shoulder '14, with which the roer end o the lociri ngbolt engagcs,wi th a slot Z5, Fig. 24, for 'the ejector, with a slot Z lfor the rear end of the trigger-engaging lever I, with aspx-ing Z7 for holding the scarl in engagement/With the ring-pn, with relatively-non- `movable shell-stops Z, Figs. 1 and 12, with a spring-held magazine shell-Stop Z9, (shown in dotted lines in Fig. 8,) and with guidegrcoves 1310, Fig. 12, for engaging iaoges on 'the rear extension of the fore'arm.

lt Wiil be understood that since thcetock stands still at discharge while the receiver moves baci; and down in virtually inclined guidera the trigger-guard is swung downwardly somewhat about the pin f2, thereby forciiig 'the fore-arm extension Jl forward. "With the exception of the slight movement thas given to the fore-arm the latter remains stationary during the recoil, and soforms a practically immovable forward extension of the stock, affording a grip for the reet-haud.

The carrier F preferably has a rearwardly and downwardly inclined surface for the shell to lie in, is provided'with guide-lugs m, which move in the grooves Z of the receiver; with wings m, liavingiuclincd, rear edgesvfor engagement by the brcech-block to be lowered thereby; with a spring-held lugm2 for operating the magazine shell-stop, and with a groove m3 in the upper surface of the bottom, with which the lower extractor member of IXO the breech-block engages to effect the initial lowering movement of the carrier.

The carrier-actuating lever F is of bellcrank; form and provided at its rear end with a gear-sector which-engages ivith'a geareector on the part F2. The part F2 ie pivotcd im the receiver on a pin n and slotted to receive a pivotd pawl'fnf, which is caused to project at its rear end by a spring n2. Inthe rearward movement the breech-block slides over the pawl n; but in the forward movement a shoulder at the pivoted end of the pat/l is caused to engage the front wall of the slot in the part F2 and rotate said part, therel by moving the carrier-actuating lever.

The breech-block is provided with a fixed. lug p, on which the shclldlange rests, and a springheld Vmovable@nem-bordi forfcatching upon the shell-flange. The lugp enters the slot m3 of the shell-carrier during the forward movement of the breech-block and causes the initial depression of the carrier. The breechloclris further provided with an inclined perforation p2 for the iriug-pin, the main full lines in Fig. 12,) carried by the locking-- bolt H. The locking-bolt is of arched form and pivotally connected to the breech-block, being provided for the purpose with trunnion-lilre lugs p, which ii't into corresponding,r sockets in the breech-block. The breechblock is cut away back of its front end or head to receive the locking-bolt, asl shown. The ioclring-bolt has a shorlfler p10 for engagging' the shoulder Z4 of tno receiver. The lug 238 has aronnded or beveled rear lower corner, so thaigjits iirst eilect when the lool;- ing-bclt is drawn down ont of the lockingl position is to cansevthe firing-pin tomove backward slightly and the lugr p8 t0 engage the shoulder p7 on the tiring-pin. The lug ps remains in the path oi' the shoulderloi until the breech-block has been reciprocated and reclcsed, after which the locking-bolt is caused to swing upward to the locking position.

Figs? 8, il, and l2 chow the breech-block provided with a slo'tpu for receiving the pawl n' of the part F2, said slot being discontinued a short distance to form a lngp12 for operating the partit in one direction through the medium of its pawl, Fig. l2 shows the breech-block provided with guide-dances p13,

and Figs. 9, il', and 13 shewa slot p14 for the actuating arm\oi` the ejector, which runs through both breech-block and locking-bolt and turns downwardly at its rear end to permit said arm to enter as the locking-bolt 'f cesscs pw swings downwardly. At its frontend the slot J is discontinued to aliorda lng p1? for moving said, actuating-arm. Fig. 9 show:y the fron-t end of the breech-block provided with rcprevent interference between breech-block and carrier and with shoulders p17 for engaging the inclined surfaces of the wings in' of the carrier to depress the carrier.

The ejector, Fig. 2i, comprises a fixed hanged slotted piece g, which tits in the slot receiver by a screw q,

Z of the receiver, an arm q', pivoted to said piece ona vertical pin q2, a lug '(13, pivoted on the same pin in a slot Qi in the arm (j, anda spring Q5, secured to the Ipiece q and to the The spring bears against the llat surface of a. lug at the rear l' end of the arm'q' and also against an adjacent fiat surface of the lug,` (f, and thus serves 'to hold the long arm of the cj feter sheathed `the recess c4.

and-'the' newbie een am. (initiieren: angles thereto. A shoulder on the Ingengages the rear wall of the slot g4, and a snrface Q7 at an angle to the fiat surface normally in engagement with the spring serves to restore the lng to its normal position after it has been sheathed in the slot o" during the forward movement ofthe breechblock. The rear ends of the (top and bottom) flanges of the piece .f1 are provided with beveled surfaces (P, which engage corresponding beveled surfaces at the rear end of the slot Z5, thereby rendering one securing-screw sufiicient.

As shown in Fig. 23, the fore-arm J is of circular section and provided with an upper groove for the lower portion ofthe barrel. As the fore-armis about ten inches in length in the ordinary shotgun, itis necessary to provide its front end with a slot r for the shellfollower button o3 to move in, as shown in said figure. The button does not project quite iiush with the surface of the fore-arm, 9o

whereby it is permitted to move beneath the hand. As shown in Fig. 8, the extension J is provided at its front end with an integrally-formed magazine-encircling band r2, to which the fore-arm is secured by screws r3.

The operation is as follows: The magazine is filled by movingitlie shell-follower toward the muzzle bymeans of the button c3, locking said button in the recess c, disengaging the connectingPv member Dand sliding it forward till it is wholly on the part D, swinging the movable portion l')4 of said magazine on its pivot to expose the open end of the lixed part D3, and finally inserting the shells into the part D3, then reconnecting the parts of the magazine and releasing the button c3 from The first shell may be introduced into the carrier by Workingthe magazine shell -stop by hand.' The barrel may then be charged' by resting the stock against the body and pulling back on the barrel to setthespringld? Duringthis movement the pinion K7 will run idly in'its rack. In the return movement caused by the spring M2 the pinion will, through the medium of itspawl .roo

and the ratchet-wheel K8, revolve the shaft K, gear K5, pinion K4, and crank K3, and thu's positively reciprocate the breech-block,there by setting the firing-pin and operatingthe ejector, carrier, and magazine shell-stop. At each discharge the recoil moves the `barrel, maga zine, receiver, breech-block, and reciprocating mechanism carried b v the frame, back, compressing the spring M2. The spring reacting restores these parts to their former position relatively to the stock, and during the restoring' movement the rack in the stock aotuates the-,reciprocating mechanism on the receiver. The movementof the breech-block extracts the shell, ejects it through a'suitable opening (not shown) in the side of the receiver opposite the ejector, elevates the carrier, inserts a new shell, lowers the carrier, moves the magazine shell-stop to recharge the carrier, and sets the iringpin against lts spring ready for discharge. It is to be noted that when the receiver moves vhack the crank Ka is moved clear of the bu der P and is thus left free torevolve during' the forward movement. By the time the crank has completed a revolution it has been carried forward far enough to engage again the bilder. As the crank descends to its normal position at rest it engages an inclined projection on the spring Q and moves the spring.

The latter reacting causes the abrupt lower shoulder of the projection to engage and lock the crank, as shown in Fig. 19. The first angular movement of the crank causes the link K to dravffv the locking-holt H" ont of cn gagement with the shoulderlof the receiver and the lug p8 to engage the shoulder p7 of the firing-pin, as esplained. As the breechhlock moves back in :its receiver the spring,r Z7 forces the scar I into engagement with the shoulder ps of the ring-pinio permit movement between the seai- :ind lever l', piu-and-slot connection is used, as shown in Fig. `S. During.: its movement the receiver slides over the upper end of' the trigger, as more readily appears from Fig. i.

In Fig. 25 I have shown a modiiicd forni ot' trigger with which it may oe desirable to equip certain rea rms t'o preventan involuntary second discharge of the weapon before nc pressure ot the, finger can hc removed from the trigger. In this form the upper portion of the trigger is made hollow to receive a spring-held plunger which is provide/l with the uptnrned rearend for engaging the lever i". 'lhe receiver is provided with an inclined g; 'inve .rf' to receive said npturncd end, and a tr verspring cgis provided for restoringr th after the finger-pressure is removed. .is the receiver moves forward alter the recoil ilul upturned end of the part .f enters thi` slet .1* and is engaged by the ilem'nturnetl cnil of the lever I'. This compresses the spring cl :he part zr, and :ittcr the trigger has heen released and moved 'ny its springr the part. ce is forced out to properly engage the end of the lever as will be readily understood. -f'

Various changes in details ol" ron.-truction"" within the spirit o." my invent ion may in* made. For instance, the locking holt or linlt l ll when used should carry menus for locking the breech-block; lint it is not essential that this means be formed integrally with thc part Il'. So the mechanism l'or reciprocating the hrecch-hlock may be varied; but it is important that thc breech-block shall he positively actuated in both. the opening and closing;` movement, as distinguished from thc actuation (in opening) in one direction hy the recoil. Preferably the entire reciprocation ot' the block occurs after the recoil and during the restoring movement. It is to be noted that the distanccof movement of the barrel, receiver', and breeclrbtock under the recoil is only a fraction of thc distance of movement ofthe breech- .vough its rcciprocating, mechanism.

-niovable on the st The breech-block is kept locked during' the.

recoil, and no harmful separation of 'parts occurs, therefore, during the recoil.

The term stock7 as used in the appended claims is meant to cover any form of support for the barrel and receiver. In a broad sense the mechanism as a whole for positively moving the breech-block is recoil-started. In a more limited sense such mechanism as is carried by the receiver and immediately connected with the breechfolock is started by the device carried by the stock.

What claim as new, and desire to' secure by Letters Patent, is`- l, in a lirearm, 'the combination of steelt, a barrel, receiver rigid n 't3-h the barrel and ook, a hreecl'i-hleclt said receiver, niechan nu carried by the receiver for reciprocating' said block, spring; for storing the receiver to its normal, posit-ion, and rack-and-pinion connection between said stock said mecha sin, whereby' mechanism is caused 'to positively recipro the brceclrbiock during; the movement the receiver, snhstautially as and for the purpose set forth.
